## Abstract

A brake device for a bicycle includes a brake arm and a stud pivotally coupled to the brake arm. The stud includes a ring and a head formed in one end. A casing has an opening and a notch formed in each of the two ends. The ring is rotatably engaged in one of the opening for allowing the casing to be rotatably coupled to the stud. An elbow has an extension for rotatably engaging in the other opening and for allowing the elbow to be rotatable about the extension such that the brake device may be attached to different place of the bicycle.

## Claims

### Claim 1

A brake device for a bicycle comprising:
a brake arm including a lower end for pivotally coupling to the bicycle frame and including an upper end,
a stud including a first end pivotally coupled to said upper end of said brake arm at a pivot pin and including a second end having a ring and a head formed thereon, said ring and said head having a size larger than that of said stud,
a casing including a first end having a first opening and a first notch formed therein and communicating with each other and including a second end having a second opening and a second notch formed therein and communicating with each other, said first notch including a smaller size than that of said first opening for engaging with said stud and for allowing said ring to be engaged with said opening, said ring including a size slightly larger than that of said first notch and including a size corresponding to that of said first opening for rotatably engaging in said first opening and for preventing said ring from being disengaged from said casing and for allowing said casing to be rotatably coupled to said stud, and
an elbow for guiding a brake cable, said elbow including an extension having a size corresponding to that of said second opening for rotatably engaging in said second opening and for allowing said elbow to be rotatable about said extension.

### Claim 2 (depends on 1)

A brake device according to claim 1, wherein said upper end of said brake arm includes a channel formed therein so as to define a pair of flanges, sad stud includes a block formed in said first end for engaging in said channel and for engaging with said pivot pin.

### Claim 3 (depends on 1)

A brake device according to claim 1, wherein said upper end of said brake arm includes a bulge formed thereon, said stud includes a groove formed in said first end for engaging in said bulge and for engaging with said pivot pin.
